Be it known that LWVILLIAM'FJPnRsoNs, a citizen of the Unltedstates, residing at I Cleveland, in the county of Cuyahogaand State of Ohio, have 'invented'a certainznew and fuseful Improvement inside Lamps for Automobiles, of which the 7. following is a full,. clear, and f exact description; reference being had to the accompanying drawings;

This invention relates .generallygto auto to the casing and another objectis to soconstruct such means that they may be quickly andeasily released whenever itis desired to replace the glass or the electric bulb.

Another object is to so construct such fastening means that they will not detract from the attractiveness or ornamentation of the design of the lamp as a whole.

vVith these various objects in View, the invention consists in the details of construction of the various parts and in the manner of combining or arranging the same all of which will be fully described hereinafter and set forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is a vertical sectional view of a lamp embodying one form of my invention; Fig. 2 is a face View of the same, Fig. 3 is a detail View of the securing ring, Fig. 4; is a fragmentary sectional view taken on the line 4-4 of Fig. 1 and Figs. 5 and 6 are similar views of slight modifications.

In carrying out my invention, I employ a lamp casing A which is substantially cylindrical in shape and at its front open end is formed with an offset or shoulder flange B which forms the seat for the edges of the lens or glass C, which lens or glass is preferably made translucent either in the composition of the glass or by grinding or sand blasting. For the purpose of holding the lens or glass firmly seated I employ a. channeled ring frame or door D of sheet metal, the inner forward edge D of which contacts with or engages the front face of the glass or lens adjacent the edges thereof and the rear edge D of said channeled ring or 1922. Serial No. 642,4 14.

' a dividedespring' ring E which? serves as a wedge and: securely holds the frame or door 111' ZPOSlt I'OII -HPOD.lZ-llB casing and 'agalnst. the

glass; said" ring resting ag ainst the 1 shoulder- I ed front "of the casing and? the 'contractedgon tapering portion of :theframe:

The ends of; the :ringrare turned outward- 1y as indicatedat Ez. and provided -.with

small: sknlobsor handles and at the bottom Ofitl'lea ring -or-z frame :the rear. portion thereof ;is scutaway as indicated=at.=I).- in

orderzthatthe ends..E.. may projectfltherethrough, said ends engaging the edge D of said cut-out portion as is most clearly shown in Figs. 1 and 4. When the ring is thus expanded it securely unites the ring and casing inasmuch as it wedges these parts securely together. When the spring ring-is contracted by bringing the knobs or handles together, its circumference is materially reduced and likewise its diameter and the ring or frame can then be quickly and easily removed from the lamp casing. for the purpose of replacing the electric bulb or replacing the glass in the front of the casing.

In assembling the parts, the spring ring is first placed around the casing just at the rear of the flanged or shouldered front thereof, the glass is then placed in the ring or frame and then the shouldered front of the casing is placed Within the ring or frame or the ring or frame is placed over the shouldered front of the casing and the ends of the spring ring are then brought towards each other and inserted in the cut-out portion D and permitted to spring into engagement with the ends thereof. The casing, glass, frame and spring clamping ring are thus securely connected together.

In the form shown in Fig. 5 the frame D is cutout at D and D in such a manner that a wedge shaped part D is formed between the cut portions D and D The extensions E of the ring E extend through the openings D and D When the ring E is contracted by bringing the knobs E together the extensions E will rifle on the faces 1) of thewedge D,

and ring will be forced rearwardly out of engagement with the lamp housing A and frame D. I

Fig. 6 shows cam slots D used in place of the parts D to D described above, which will act in the same manner as the form just described. The slots D are enlarged at D for convenience in assembling.

It will thus be seen that I provide a simple and highly efficient form of side light equal of carrying out all of the objects of the invention hereinbefore referred to.

Having thus described my invention, what I claim is v I 1. The combination with a lamp casing having a shouldered front edge, of a glass seating upon said shouldered edge, a channeled ring or frame surrounding the shouldered edge of the casing, the forward inner edge of said ring or frame contacting with the-front face of the glass, the rear edge of said ring or frame being inclined toward the casing, anda divided spring ring interposed between the shouldered edge of the casing and the inclined or contracted edge of the ring or frame, said spring ring hav- 'ing outwardly projecting end portions each passing thru an opening or notch produced in the rear edge of the ring or frame, an edge portion of the opening or notch being so formed that the spring ring is forced rearwardly thereby when its end portions are drawn toward each other.

2. The combination with a lamp casing having a shouldered front edge, of a glass seating upon said shouldered edge, channeled ring or frame surrounding the shoul dered front edge of the casing, the forward inner edge of'said ring or frame contacting with the exterior of the glass, the rear edge of said ring orframe extending rearwarcly '.beyond the shouldered edge of the casing and inclined toward the casing and a divided spring ring interposed between the shouldered edge of the casing and the rearwardly extending inclined edge of the ring or frame, the ends of said ring projecting radially outwardly'through an opening in the ring frame, said openin extending rearwardly whereby when the end portions of the spring ring are drawn together said portions will be caused to move rearwardly.

In, testimony whereof, I hereunto afliX my signature. 7
